Beyonce' and Pepsi released a commercial on Thursday, April 4 the same day of her fifth wedding anniversary. The television spot is the first ad for her lucrative $50 million deal the songstress and beverage company announced in December.

On Sunday, an Instagram account with the name Found Hov posted a photo of a sheet of paper on the social media site with what appears to be the full lyrics to Beyonce's as-yet-released single on Sunday.

The "FoundHov" user wrote the following caption attached to the photo: "#sneakpeek#grownwoman#thesingle don't snitch, lol. Will be released on iTunes and the radio tomorrow."

Grown Woman is featured in Pepsi's 20-second spot for the Pepsi Max drink titled Mirrors. The commercial was directed by Beyonce's frequent music video collaborator Jake Nava. The clip features the Bootylicious singer taking a look at herself as various egos of herself from previous music videos wearing several different wardrobe changes throughout the course of several years. In one scene, she wears the infamous robot metal glove she wore in her Single Ladies music video.

Beyoncé said in a statement that she had "so much fun" filming the spot because she had the chance to "relive" some of her favorite fashion moments in the spot.

"I got to relive some of my favorite past characters and looks. It was the first time I saw those costumes in years and it was very emotional," she said. "I'm proud of those moments and they all connect in some way and have helped me evolve into who I am today."

Here are the partial lyrics to Grown Woman featured in the Pepsi Max commercial:

They like the way I walk cause I walk with a vengeance/ And you listen to me when I talk cause I ain't pretendin

Took a while now I understand just where I'm going/ I know the world and I know who I am 'bout time I show it/ And I'm moving down like that when I do it."

The single, Grown Woman, was produced by super music producer Timbaland who has had success putting out a bevy of hits for over a decade with mega-artists such as Justin Timberlake's last two albums, including Sexy Back
